ABSTRACT

Objective@#To investigate the relationship between workplace bullying and posttraumatic stress disorder (PTSD) in nursing staff, and to analyze the role of psychological capital between workplace bullying and PTSD.@*Methods@#From December 2014 to June 2015, convenience sampling was used to collect 496 nurses from 5 grade A tertiary hospitals in a province of China. Their workplace bullying, psychological capital, and PTSD status were assessed using the Negative Acts Questionnaire, Psychological Capital Questionnaire, and Posttraumatic Stress Disorder Self-Rating Scale, respectively. The correlation between variables was analyzed using a structural equation model.@*Results@#Among these nurses, the scores of negative acts, psychological capital, and PTSD were 37.15±12.83, 78.81±16.54, and 34.56±12.52, respectively. The score on each dimension of negative acts was positively correlated with that on each dimension of PTSD (P<0.01) ; the score on each dimension of psychological capital was negatively correlated with that on each dimension of PTSD and negative acts (P<0.01). Negative acts had a positive predictive effect on PTSD (β=0.539, P<0.01) , which was reduced after inclusion of psychological capital (β=0.513, P<0.01). The path coefficient was 0.62 for the effect of negative acts on PTSD, -0.18 for the effect of negative acts on psychological capital, and -0.11 for the effect of psychological capital on PTSD (P<0.05) .@*Conclusion@#Workplace bullying is a predictive factor for PTSD, and psychological capital plays a mediating role between workplace bullying and PTSD. The manager should reduce workplace bullying to improve the psychological capital in nursing staff and to prevent and reduce PTSD.

ABSTRACT

Objective To explore the relationship between posttraumatic stress disorder and nurses′ psychological capital. Methods By convenient sampling, totally 550 nurses in 5 first-class upper level general hospitals in Zhejiang province were investigated by the posttraumatic stress disorder (PTSD)Cheeklist-Civilan Version (PCL-C) and Nurses Psychological Capital Questionnaire Revision (NPCQR), and the results were analyzed. Results 18.35%investigated nurses showed a certain degree of PTSD symptoms and 13.71% showed obvious PTSD symptoms. The positive rate was 32.06%.The overall score of nurses′psychological capital was 78.81 ± 16.54, which was in the middle level, and the dimension scores from high to low were self-efficacy (23.80±5.35), hope (23.36±5.24), resilience (19.66 ±4.29), and optimism (11.99 ± 3.21). The nurses′psychological capital had a negative effect on posttraumatic stress disorder (P<0.01). Conclusions Psychological capital of nurses is a negative predictor of PTSD symptoms, which suggested that managers should pay more attention to the development of nurses′psychological capital to reduce and prevent the occurrence of posttraumatic stress disorder,then to improve nursing service quality.

ABSTRACT

Objective To investigate the correlation between ICRU reference point dose and dosevolume parameters of organs at risk (OARs) under different bladder and rectal filling status in threedimensional conformal brachytherapy for locally advanced cervical cancer.Methods A total of 31 patients who received magnetic resonance imaging-guided three-dimensional conformal brachytherapy for cervical cancer in 96 fractions were enrolled.The ICRU rectal and bladder reference points were determined in the treatment planning system,and the doses at these points were recorded and compared with the dose-volume parameters of the rectum and bladder.The paired t-test was used to analyze the differences between them.Results Bladder DICRU was lower than bladder D0.1cm3 and D1 cm3 (P=0.000 and 0.000),higher than bladder D5 cm3 and D10cm3 (P=0.000 and 0.000),and similar to bladder D2 cm3 (P=0.345).Under the bladder filling status,bladder DICRU was lower than D2cm3.Rectal DICRU was lower than rectal D0.1 cm3 and D1cm3 (P =0.000 and 0.002),higher than rectal D5 cm3 and D 10 cm3 (P =0.000 and 0.000),and similar to rectal D2cm3 (P=0.058).The ICRU bladder and rectal reference point doses were positively correlated with corresponding D2 cm3.In the case of bladder volume ≥ 200 cm3,the ICRU bladder reference point dose underestimated bladder D2 cm3.In the case of rectal volume ≥ 37 cm3,the ICRU rectal reference point dose overestimated rectal D2 cm3.Conclusions In three-dimensional conformal brachytherapy,it is generally safe to use D2 cm3 as an index to evaluate OARs,but when the bladder or rectum is in an empty status,the ICRU bladder or rectal reference point doses should be considered.
